The getOffset(int era, int yr, int mon, int day, int dayOfWeek, int millisec) method of TimeZone class in Java is used to know the offset value of this TimeZone at a specific date or modified date in case of daylight savings, from the UTC or the Universal Time Coordinated. This offset value can be added to get the local time.
Syntax:
public abstract int
getOffset(int era, int yr,
int mon, int day,
int dayOfWeek, int millisec)
Parameters: The method can take the below mentioned parameters.
- era: This is of integer type and refers to the era of the given date.
- yr: This is of integer type and refers to the year in the given date.
- month: This is of integer type and refers to the month in the given date.
- day: This is of integer type and refers to the day-in-month of the given date.
- dayOfWeek: This is of integer type and refers to the day-of-week of the given date.
- milliseconds: This is of integer type and refers to the milliseconds in day in standard local time.
Return Value: The method returns the offset value in milliseconds that can be added to GMT to get local time.
Below programs illustrate the working of getOffset() Method of TimeZone:
Example 1:
// Java code to illustrate getOffset() method  import java.util.*;  public class TimeZoneDemo {    public static void main(String args[])    {          // Creating a TimeZone        TimeZone offtime_zone            = TimeZone.getTimeZone("Europe/Rome");          // Checking the offset for the systems date        System.out.println("The Offset Value is:"                           + offtime_zone.getOffset(                                 1, 2018, 5, 12, 2, 500));    }} |
Output:
The Offset Value is:7200000
Example 2:
// Java code to illustrate getOffset() method  import java.util.*;  public class TimeZoneDemo {    public static void main(String args[])    {          // Creating a TimeZone        TimeZone offtime_zone            = TimeZone.getTimeZone("Pacific/Pago_Pago");          // Checking the offset for the systems date        System.out.println("The Offset Value is:"                           + offtime_zone.getOffset(                                 1, 1995, 9, 20, 2, 700));    }} |
Output:
The Offset Value is:-39600000
